One of the methods of surface preparation is degreasing (cleaning), which can be realised using various methods and degreasing agents. Supreme 11AOHT-LO. Apart from such complexities, adhesives are extremely varied in their form, chemistry and mode of use. For adhesives, the suitability for structural bonding is indicated by either European standard EN 301 (phenol-based and amino resin adhesives), EN 15425 (polyurethane adhesives) or EN 16254 (EPI adhesives), where EN 301 and EN 15425 type I adhesives are suitable for all Use Categories (1, 2 and 3), and Type II adhesives and EN 16254 Type I adhesives are for Use Categories 1 and 2. Epoxy (meth)acrylates These resins provide an outstanding stiffness and high Tg in combination with chemical and hydrolysis resistance. A:Structural adhesives generally prefer clean, rough, dry surfaces for highest bond strength. This typically means either light abrasion and solvent cleaning of the surface, or solvent cleaning followed by chemical etching or applying a primer. Adhesive polymer toughness may be increased by blending, filling or co-polymerising it with a tough polymer to improve impact and low temperature performance; this will cause a reduction in strength of the adhesive and in this situation it is necessary to compromise between strength and stiffness. Dear valued customer, we are fully operational with all departments in attendance. Adhesives containing woven cloth may have slightly degraded environmental properties because of wicking of water by the fiber. The local stress introduced at each fixing point will be eliminated. Adhesive bonding represents the natural method for joining together dissimilar materials such as concrete, or metals or timber and polymer composites. A structural adhesive can be simply described a ‘high-strength glue’ that bonds together components in a load-bearing structure. There are many aspects which must be considered, including the storage of materials, protection of the working environment, surface preparation of the components, adhesive mixing, dispensing and application, joint fit-up, bondline thickness control and curing. The authors wish to express their thanks for the assistance given, and permission to include examples showing the application of adhesives in this chapter, by Loctite UK – www.loctite.co.uk. J.F.

Thank you for your support and understanding. +44(0)1162894655 enquiries@structuraladhesives.co.uk, Units 12 -13A Marlow Road Industrial Estate, Leicester, LE3 2BQ Structural adhesives are usually proprietary formulations, and while the manufacturers will supply details of properties, method of use and generic type, details of composition are not necessarily disclosed. Quite frequently two types of monomer will be mixed, and the hybrid polymer that results may have better properties than its parents. Structural Adhesives for the Aerospace Industry One and two component epoxy compounds have been developed for aerospace bonding, potting, filling and repair applications. The essential requirements for structural adhesives are: The selection of a suitable adhesive polymer. As with the laminating resins, there are two types of adhesives, the cold- and the hot-cured polymers. To optimise the adhesion of the adhesive and the adherends and the performance of the adhesive joints in the surface treatment is critical stage of bonding technology. Structural adhesives, which are categorized by their chemistries, are routinely capable of overlap shear strengths of more than 1,000 psi when bonding metal in room-temperature testing. The lower strength and modulus mean that silicones are excellent for repair and rework applications and are ideally suited for applications that require a certain level of stress flexibility in the adhesive joint. Also ideal for bonding stone or concrete containing moisture. In Introduction to Aerospace Materials, 2012. This is facilitated by ensuring that operatives, and their supervisors, undergo training in adhesive bonding so that a clear understanding is developed of the standard of surface preparation that must be achieved. Adhesives are most commonly used in joints of thin aerostructures with a well-defined load path. Above and under water cure capable system. Service temperature range from -60°F to +250°F. With the correctly formulated polymers, possible to obtain operating temperatures in the range − 30 °C to + 60 °C for site service life. Three methods of degreasing: rubbing, spraying, and immersion and five types of degreasing agents: acetone, extraction naphtha, Loctite 7063, Ultramyt, and Wiko were used in experimental test. 3.1).

Structural Adhesives form bonds that will not fail when a bonded joint is stressed to the yield point of the material being bonded. They can produce a much better finished appearance to an assembly than, say, rivets, or spot welding or screws. In general, toughening a resin results in a lower usable service temperature. Read about how epoxy adhesives, like the 3M™ Structural Two-Part Adhesive, can be an efficient way to modernize your product design without compromising quality or durability. SikaPower®-877 is a structural two-component epoxy adhesive, which cures at room temperature. A well-prepared adherend surface; this is a very important aspect in adhesive bonding, it might be necessary to use a coupling agent on the surface of the concrete substrate. Further information on adhesive bonding may be obtained from Mays and Hutchinson (1992), and on the structural use of adhesives from the Institution of Structural Engineers, UK (1999). Tough and resilient. A.R. Especially recommendable when fast curing is required. Film adhesives are preferred to liquids and pastes because of their uniformity and reduced void content. They behave as a liquid during their application, which is important in order to achieve good wetting of the substrate surfaces, and cure to form a high molecular weight, rigid, cross-linked, solid elastomer. The standard for strength, durability and outdoor weathering ‘Epoxy’ is often used as a generic term for a structural adhesive, but epoxy adhesives are actually a very specific class of structural adhesives. 3.1. Fraunhofer IFAM in Bremen, Germany (Klebtechnisches Zentrum) has offered a university level education in structural adhesive bonding since 1994. By nature, silicones have lower cohesive strength than other structural adhesives such as epoxies; however, this property is an advantage in a number of applications. It should activate and increase the surface free energy of adherends and the active bonding area to improve the adhesion of the adhesives. (1998) have provided ‘A Best Practice Guide’ for the assessment of adherend surface quality and guidance on the definitions of surface quality. VAT Registration No. There are various types of structural adhesives, including epoxy adhesives. A low creep and good strength retention under sustained load. In order to promote adhesion, the surface of adherends must be properly prepared for joining. It is designed for high strength and impact-resistant bonding of metallic substrates, like steel and aluminum, as well as of composite substrates like glass fiber reinforced and carbon fiber reinforced laminates. If you need an adhesive for furniture, handicrafts, or woodworks, choose Pioneer Epoxy. The degreasing can be applied either by itself or in combination with other methods, e.g. A structural adhesive is a substance that fastens together elements to produce high modulus, high strength, permanent bonds. , in Advances in Structural Adhesive Bonding, 2010. Thixotropic self-priming epoxy adhesive for structural strengthening using CFRP laminates and steel plate bonding Sikadur®-300. Film materials are frequently supported by fibers (scrim cloth) that serve to improve handling of the films prior to cure, control adhesive flow during bonding and assist in bondline thickness control and provide galvanic insulation.

Key performance issues (Hutchinson et al. Protecting the joint from unacceptably hostile conditions in service. For design purposes, actual properties must be obtained from the manufacturer. Fibers can be incorporated as short-fiber mats with random orientation or as woven cloth. • Can the surface be prepared such that a sufficient level of adhesion is obtained? This chapter describes a wide variety of polyurethane (PUR) adhesives and how adhesive bonding technology can be used successfully by engineers. Result: rigidity; unblemished exterior surfaces. It is applied with conventional silicone guns. As such the adhesive is part of the structure of the assembly. Structural adhesive joints depend on the interfacial relationship of the adhesive and the adherends. Random mat scrim cloth is not as efficient for controlling film thickness as woven cloth, because the unrestricted fibers move during bonding, although spun-bonded non-woven scrims do not move and are, therefore, widely used. S-2682E + Structural Chemical Resistant Sealant/Adhesive. Adhesive bonding represents the natural method for joining together dissimilar materials such as concrete, or metals or timber and polymer composites. The requirements for a satisfactory joint performance are: Good contact between the adhesive and the substrate. As the term implies, adhesives work through the process of adhesion. A low shrinkage (residual bond-line strain in cured joints is reduced). Lancaster, in Metallurgy of Welding (Sixth Edition), 1999. Passes NASA low outgassing tests. Epoxy and structural adhesives create an industrial-strength bond that eliminates the need for most fasteners. FIGURE 36.13. rust and various kinds of contaminations from the surfaces to be joined. Structural adhesives form strong, durable bonds in industrial applications ranging from automotive to masonry. From kitchen appliances and sporting goods to automobiles and aerospace, our wide variety of structural adhesives includes options to meet your design and manufacturing needs. Furthermore, adhesives prevent the corrosion problems normally associated with joining dissimilar materials. Anna Rudawska, in Surface Treatment in Bonding Technology, 2019. • Can the adhesive transfer the load between the substrate and the reinforcement for the design lifetime. Fill the void beneath motors, pumps, and other large machinery to create a structural support for your equipment. The upper temperature limit of 250–350 °F is usually dictated by the degree of toughening required and by the overall choice of resins and curing agents. Structural adhesives have a long history of use in construction, with epoxy adhesives having been exploited for externally-bonded steel plate reinforcement since the mid-1960s. The adhesive may be used without modifications in normally fitted joints, and will cure without shrinkage. Structural epoxy adhesive for secondary laminations, even under extreme temperature conditions (very low) and high humidity. CAB-O-SIL ® fumed silica provides reinforcement and rheology properties to epoxy and polyurethane adhesives and sealant systems for an array of applications including structural and elastic bonding, commonly used in wind turbine blades, and industrial and automotive assembly. They are therefore not easily lumped into categories, and are considered individually below. Cures at room temperature. If post cured, otherwise the value will be dependent upon the environmental temperature at the time of curing. This chapter describes the essence of degreasing operation, the characteristics of degreasing methods and also the properties of some degreasing agents. The latter need typically arises when the adhesive joint must be capable of absorbing a certain amount of movement, for instance, resulting from differences in thermal expansion between the substrates, vibration of the components, exterior loads, and so on. Structural Adhesives – Epoxies. Also included are designation examples and the dimensioning of graphical symbols. thus, it substantially contributes to the structural integrity of continuously stressed assemblies during their expected service lives under relatively severe service environments.
